DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book case type storage case for storing a disk cartridge such as an optical disk.

[0002]

2. Description of the Related Art One of such disk cartridges is a mini disk (hereinafter simply referred to as MD). The storage case for the MD is formed in a thin rectangular box shape, and an entrance is provided on the front side surface of the case to form a book case. A pair of locks are built into the inner side of the left and right side walls of the case. The MD is inserted into the storage case, and both locks are dropped into the positioning recesses on both sides of the lower surface of the cartridge case to engage with the MD. Slipping from the case can be prevented.

[0003] The index card is stored inside the storage case together with the MD. However, since the opening width of the entrance is as small as about 5 to 6 mm, when the MD is pulled out from the storage case,
The index card may be pulled out at the same time. MD
In a state where the index card is pulled out of the storage case, the sheet-like index card may slide down from the entrance.

In order to solve the above-mentioned problems, the present applicant has previously proposed a storage case in which stoppers for receiving an index card are provided on both side edges of an entrance (Japanese Patent Application No. 8-295646). ). Furthermore, ribs for retaining are projected over the entire width of the opening edge of the entrance,
A storage case that prevents the index card from slipping out with this rib is also proposed.

[0005]

As described above, according to the storage case in which the ribs for retaining are projected, it is possible to prevent the index card from being pulled out together with the MD. However, when the operation was confirmed using a storage case having ribs for retaining, a new problem was found to occur. M
D is provided with a shutter for slidingly opening and closing the signal reading window. When the MD is extracted, the edge of the shutter is received by the preceding rib and is caught. It is easy to get caught especially when the index card is not stored. The present applicant has proposed a storage case composed of a case body and a lid capable of slidingly opening and closing the upper surface of the case body in order to facilitate taking in and out of the MD. In the case, it has been confirmed that the edge of the shutter is easily caught. This is because, when the lid is slid open and then the MD is slid out of the entrance while sliding, the sliding recess of the shutter is pressed against the protruding end surface of the rib, and the shutter edge comes into contact with and engages with the rib.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent an index card housed together with a disk cartridge from being carelessly ejected when the disk cartridge is taken out, or to prevent the index card from slipping out of the case. An object of the present invention is to provide a storage case for a disk cartridge which can be taken out without trouble even if the disk cartridge has a shutter. SUMMARY OF THE INVENTION An object of the present invention is to provide a storage case having a lid that can be slid open and closed, so that when the lid is opened and the disk cartridge is removed without any trouble, the disk cartridge can be reliably removed without any trouble. It is in.

The disk cartridge 1 provided with a shutter 5 for opening and closing the signal reading window 4 is to be stored. The disk cartridge 1 includes a case main body 10 having an open upper surface, and a lid 11 for closing the upper surface opening of the case main body 10. It is configured as a book case type in which the entrance 12 for the disk cartridge 1 is opened on the front side surface. A rib 37 for receiving an edge of the index card C on the entrance 12 side on the inner wall of the opening of the entrance 12.
To protrude. An escape area E that avoids contact interference with the edge of the shutter 5 is secured at the side end of the entrance 12. The rib 3
Reference numeral 7 protrudes from the escape area E.

More specifically, escape areas E are secured on both side ends of the entrance 12 and ribs 37 protrude along the inner wall of the opening of the entrance 12 between the escape areas E. The lid 11 is a slide mechanism provided between opposing surfaces of the side wall 15 of the case main body 10 and the lid side wall 19 of the lid 11, and is guided and supported so as to be slidable back and forth so that the second opening 17 on the upper surface of the case can be slid and opened. . The slide mechanism includes a guide groove 22 provided on the inner surface of the side wall 15 of the case body 10, and a shaft 21 protruding from the lid side wall 19 of the lid 11 and sliding back and forth in the guide groove 22. A rib 37 protrudes from the inner wall of the opening on the case body 10 side.

[0009]

The rib 37 protrudes from the opening edge of the entrance 12 so that the edge of the index card C housed in the storage case on the entrance 12 side can be received by the rib 37 to prevent the index card C from slipping out. Accordingly, it is possible to prevent the index card C from being accidentally pulled out together with the disk cartridge 1 or to slip out of the entrance 12 by its own weight or by receiving an external force. The escape area E is secured at the side end of the entrance 12 and the rib 37 is provided to avoid this area E. Therefore, when the disk cartridge 1 is pulled out of the storage case out of the case, the edge of the shutter 5 is moved to the rib 37. It can be prevented from getting caught. This is because the edge of the shutter 5 always passes through the escape area E.

When the escape areas E are secured at both ends of the entrance 12, the edge of the shutter 5 can be caught on the rib 37 even when the disk cartridge 1 is loaded in the storage case in an upside down posture. Can be prevented. Lid 11
When the slide release and the removal of the disk cartridge 1 are continuously performed with one hand, the case body 10 is often supported by four fingers other than the thumb. In such a case, the disc cartridge 1 is slightly pressed against the case body 10 with the thumb and is taken out. However, even in such a situation, the escape area E is secured in the entrance 12 so that the shutter 5 can be securely caught. Can be prevented.
